The properties for defining Linux-specific options that are applied to the container.
Example
declare const taskDefinition: ecs.TaskDefinition;
taskDefinition.addContainer('container', {
image: ecs.ContainerImage.fromRegistry("amazon/amazon-ecs-sample"),
memoryLimitMiB: 1024,
linuxParameters: new ecs.LinuxParameters(this, 'LinuxParameters', {
initProcessEnabled: true,
sharedMemorySize: 1024,
maxSwap: Size.mebibytes(5000),
swappiness: 90,
}),
});
Properties
Name | Type | Description |
---|---|---|
init | boolean | Specifies whether to run an init process inside the container that forwards signals and reaps processes. |
max | Size | The total amount of swap memory a container can use. |
shared | number | The value for the size of the /dev/shm volume. |
swappiness? | number | This allows you to tune a container's memory swappiness behavior. |
initProcessEnabled?
Type:
boolean
(optional, default: false)
Specifies whether to run an init process inside the container that forwards signals and reaps processes.
maxSwap?
Type:
Size
(optional, default: No swap.)
The total amount of swap memory a container can use.
This parameter will be translated to the --memory-swap option to docker run.
This parameter is only supported when you are using the EC2 launch type. Accepted values are positive integers.
sharedMemorySize?
Type:
number
(optional, default: No shared memory.)
The value for the size of the /dev/shm volume.
swappiness?
Type:
number
(optional, default: 60)
This allows you to tune a container's memory swappiness behavior.
This parameter maps to the --memory-swappiness option to docker run. The swappiness relates to the kernel's tendency to swap memory. A value of 0 will cause swapping to not happen unless absolutely necessary. A value of 100 will cause pages to be swapped very aggressively.
This parameter is only supported when you are using the EC2 launch type. Accepted values are whole numbers between 0 and 100. If a value is not specified for maxSwap then this parameter is ignored.
